Objective To compare the cl inical effectiveness of the medial plantar flap, the retrograde posterior tibial vascular flap, and the reverse sural neurocutaneous flap in repairing defect caused by resection of cutaneous mal ignant melanoma (CMM) in the heel region. Methods The cl inical data were retrospectively analysed from 24 patients with defect who had CMM in the heel region and were treated by radical excision and flap repairing between March 2007 and March 2010. Defects were repaired with the reverse sural neurocutaneous flaps of 8 cm × 7 cm-14 cm × 12 cm at size in 12 patients (groupA), with the medial plantar flaps of 6 cm × 5 cm-8 cm × 7 cm at size in 7 patients (group B), and with the retrograde posterior tibial vascular flaps of 9 cm × 7 cm-15 cm × 13 cm at size in 5 patients (group C). There was no significant difference in gender, age, duration of illness, cl inical stage, and size of CMM among 3 groups (Pgt; 0.05). The donor site was sutured directly or by free skin graft. Results No significant difference was found in the operation time and the intraoperative blood loss among 3 groups (P gt; 0.05). All skin flaps or grafts survived and wounds healed by first intention. The patients were followed up 1-3 years. The flaps had normal texture and color with no ulcer in 3 groups. At 1 year after operation, the sensory recovery rates of the flaps were 0, 100%, and 20% in groups A, B, and C, respectively, showing significant difference among 3 groups (P=0.001). The patients had normal appearance of heel and pain-free walking [10 (83%) in group A, 6 (86%) in group B, and 4 (80%) in group C] of heel region, showing no significant difference among 3 groups (χ2=40.000, P=0.135). Heel pain existed in weightbearing walking of 3 groups, and there were significant differences in visule analogue scale (VAS) score (Plt; 0.05). There was no significant difference in range of motion of ankle joint among 3 groups (P gt; 0.05). Except 1 patiant of relapse in group A at 1 month after operation, no relapse was observed in the other patients during follow-up. Conclusion The medial plantar flap, the retrograde posterior tibial vascular flap, and the reverse sural neurocutaneous flap can achieve the good cl inical effectiveness in treating heel defect caused by the resection of CMM. And the medial plantar flap is the first choice in small skin defect of heel area.
OBJECTIVE: To provide a new reconstructive method to treat refractory ulcers on the sole of the forefoot. METHODS: The reversed medial plantar flap with the medial plantar pedal artery and vein as pedicle was used to treat the refractory ulcers on the sole of the forefoot in 5 cases. The size of the flap was 3.5-5.0 cm x 4.0-5.5 cm. The deformities were corrected at the same time and the flaps were protected after operation. RESULTS: All flaps survived without complications. There was no recurrence after 6-month following-up. The patients could walk. CONCLUSION: The distal ends of medial plantar pedal artery and vein have plenty anastomoses with dorsal pedal artery and deep plantar arch. The reversed medial plantar flap has reliable blood supply by these anastomoses. The reversed medial plantar flap should be a choice in treating refractory ulcers on the sole of the forefoot.
Objective To investigate the effectiveness of modified free medial plantar flap with preserved abductor hallucis for repairing cicatricial contracture deformity of palm. Methods Between January 2012 and July 2017, a modified free medial plantar flap with preserved abductor hallucis was used to repair 9 cases of cicatricial contracture deformity at the palm. There were 7 males and 2 females with a median age of 23 years old (range, 15-40 years). The duration of cicatricial contracture was 4-23 years (mean, 9 years). In addition, 3 cases had combined stiffness of finger joints, 2 cases of tendon exposure, and 2 cases with exposed tendon and nerve. The range of flap was 4.5 cm×4.0 cm to 8.0 cm×6.0 cm. The vessel pedicle of the flap was 7-8 cm in length, with an average length of 7.5 cm. Grafting and repairing were performed with full-thickness skin graft from the ilioinguinal region in the donor site. Results All flaps and skin grafts survived after operation, and all wounds healed at first intention. All 9 patients were followed up 5-22 months (mean, 10 months). The flap exhibited smooth appearance and soft texture, which was similar to that of the normal skin around. The recovery time of dermal sensation was 5-12 months (mean, 9 months). At last follow-up, the flap recovered to level S4 in 5 cases, level \begin{document}$\small{{\rm{S}}_{{{\scriptsize 3}^ + }}}$\end{document} in 2 cases, and level S3 in 2 cases. The two-point discrimination was 6.0-10.0 mm (mean, 8.5 mm). According to the assessment of the upper limb function issued by the Hand Surgery Society of Chinese Medical Association, the hand function was excellent in 5 cases, good in 2 cases, and fair in 2 cases. Additionally, the abduction and flexion activities of the great toe of the donor foot were not affected, and the skin grafting area was slightly colored. Conclusion The modified free medial plantar flap for repairing cicatricial contracture deformity of palm has such advantages as no impact on abductor hallucis, small damage of the donor area, improved survival rate of skin grafting, and the unaffected function of the donor foot.
